Add removeCommand() and removeCommands() methods to API.

[jonnywilliamson]

Added new tests to verify the new methods.

Have also added other new tests in the new suggested format for naming. I have left the other test names alone just so we can see what both look like.

[Nitpick-CI]

Method name ApiTest::it_should_only_allow_a_string_as_the_api_token is not in camel caps format

So nitpick seems to be doing its job and i was bombarded with email notifications :|

[jonnywilliamson]

Well I'll update my snippet for tests to put a "public" visibility for each function.

As for camel case caps? Mmmm.

[Nitpick-CI]

Method name ApiTest::it_should_throw_exception_if_supplied_command_class_does_not_exist is not in camel caps format

[irazasyed]

Have to ignore camel case caps check, Let me check their docs.

@irazasyed How about adding the nitpick.json config file and bypassing the test directory?

@jonnywilliamson I just added but ignoring would completely ignore all the checks. Including like the visibility one (like it suggested) and other PSR2 violations.
